DESCRIPTION:Abstract:\n\nIndependently whether hadron or electron collider
 s detectors\, the mostprecisely measured are directions of muons\, followe
 d by  directions of electrons and later lepton energies. That is why prec
 ision requirements are defined by: size of alpha_QED necessity to define o
 bjects like intermediate bosons on one side\, and detector details: granul
 arity and background subtraction requirements on the other. There can be d
 iscussed 3 levels for  ambiguities: not better than 1 %\, around 0.3 and 
 finally better than 0.1%. They require different level of sophisticated\, 
 Field theory based theoretical predictions\, to complete tests of Standard
  Model. Agreement means confirmation and discrepancy point to New Physics 
 (or faulty calculations). As important experience I will point to  precis
 ion measurements of LEP 1 time\, where precision of  0.043% was reached f
 or theory experiment comparisons. What this experience may hint for the fu
 ture\, where for example\, FCC measurements of 0.01 % or even better ambig
 uities are expected. In particular\, What requirements of theory predictio
 ns this will require: for Monte Carlo programs\, for prediction of idealiz
 ed/optimal  observables\, possibly to be used in fits or in ML applicatio
 ns.\n\n \nImportant: This seminar is held in building D-11 room 104. \
